UNTED STATES Parent series,

ALBERT BUSH, or coLnMBUs, onIo noon FOR ELEvAToR-sHArTs.

To all whom it may concern:

Be it known that I, ALBERT BUSH, a citizen of the United States, residing at Columbus, in the County of Franklin and State of Ohio, have invented a certain new and useful Improvement in Doors for Elevator- Shafts, of which the following is a specification.

The present invention relates to the type of elevator and door shown in the patent issued to me September 9, 1919, No. 1315,?" 95 and has for its object a modification aifording advantages in some respects, one of which is that door Channels in the building can be clispensed with.

Like the Construction of my said former patent the present invention includes a support for the door on the car and in addition thereto, as distinguished from my former Construction, it includes a guiding channel for the door on the car, said channel leading to the door support on the car. Further the channel is of such Construction as to permit the passage of the car past the closed door when it is not desired tostop the car at the door.

The invention is embodied in the construction herein shown and described, the features of novelty being finally claimed.

In the accompanying drawing- Figure l is a vertical sectional view through the car and door showing their relation to the fioors of a building at the elevator well.

Fig. 2 is a horizontal section on the line II-II Fig. l, lookingdown.

In the views 5 designates the several floors of a building adjacent the elevator shaft or well and 6 an opening or doorway to such shaft. Each opening 6 is provided with a door like that shown at 7 adapted to be raised and lowered, the door being provided with suitable counterbalancing means if desired, to facilitate the operation.

The car or carriage has secured to each of its opposite sides by suitable brackets 8 a vertical guiding channel 9 extending substantially the full height of the car. The up er end, of channel 9 is prolonged and fiared for a portion of its length above the car so as to form a guide and support 10.'

The upper end of the flared portion of'the guide above the car is left with an opening 10 in one of its walls in vertical line with the Channels 9 so as to afford an unobstru-ct- Specification of Letters Patent. Patenta@ June 1, 1920 Application filed September 22, 1919. Serial No. 325444. V

Each of the doors has on 'the room side i' hooks 12 to take into sockets 713 when the 'door is closed and therefore 'prevent facewise movement of the doorbut permit it to be raised in a vertical direction. On the well side of the door at its upper and lower corners are projecting arms 14: having projecting lateral studs 15 hearing' `rollers adapted to enter the Channels when the car is brought opposite the door, as shown in Fig. 1.

When the car is brought opposite the door and stopped the channels on the car serve as guides for directing the door to the support on the top of the car as shown in broken lines Fig. l. On the other hand the openings 10 in the fiared portions of the channels permit the car to move past the door without disturbing the door at all. p

The car will, of course, be provided with any suitable means for hoisting it.

The forms of the parts can be changed without departing from the invention as e claimed.

What I claim is:

l. The combination with a building having an elevator shaft and doorways leading from the fioors of the building to the shaft and a car to move vertically in said shaft, of sliding doors for the doorways of the building, a support on the car to receive one of said doors and guiding means on the car below said support to guide the door to said support.

2. The combinatiof with a building having an elevator shaft and doorways leading from the fioors of the'building to the shaft and a car to move vertically in said shaft, of sliding doors for the doorways of the building, a support on the car to receive one of saiddoors and channels on the car below'said support to guidethe .doorto said support. i

3. The combination with a building having an elevator shaft and doorways leading from the'fioors of the building to the shaft and a car to move vertically in said shaft, of sliding doors for the doorways of the building, a support on the car to receive one of said doors,guiding means on the car below said supportand means on the door to engage said guiding means to direct the door when raised to' the support.

,4. The' combination with a building having an elevator shaft and doorways leading from the floors of the building to the shaft and a car to move vertioally in said shat, a' support on the car to receive one of said doors and guides on the carbelow said support to guide the door to the support, said guides constructed to permit the car to pass the door when closed without disturbing the same.

5. The combination with a building having an elevator shaft and doorways leading from the floors of the building toothe shaft and a car to move Vertically in said shaft, of sliding doors for the doorways of the building, a uide on the car eXtending above the top of t e car where it forms a support' for one of said 'doors when opened, means on the door for engaging said guide, said guide provided with an opening permitting the passage of the car past the door When in closed position. r

6. The comb'nation with a building having an' elevator shaft and doorways leading from the floors of the building to the shaft and a car to move vertically in said shaft, of sliding doors for the doorways of the building, a guide' on the ear extending above the top of the car where it forms a support for one of' said doorswhen opened, means on the door for engaging said guide,

said guide provided with an opening permit-' ting the passage of the car past 'the door when in closed position and latching means for preventing facewise movement of the door When in closed position.

ALBERT BUSH.
